To all whom z'tmayconcern M Be it known that LFREDERIGKD. WIL- SON, acitizen of the United States, and a resident of Moline, in the county ofRock Island and State of .Illinois, havc invented certain new and usefulImprovements in Mowing-Machines, of which. the following is aspecification, referencebeinghad to the My inventionrelates to mowingmachines and particularly to that type of machine which has itscutter-bar arranged to be lifted by means of a lever from a horizontalop erative position to a substantially vertical inoperative position,and it has for its principal object the provision of simple and im-.proved means for lifting the cutter-bar and for locking it in either ofa plurality ofraised positions and for unlocking. it therefrom. It isone of theobjects of my invem tion to provide liftingmechanism for a cutter-bar so arranged and constructed that by the manipulation of afoot-lever the cutter-bar may be unlocked: and lowered into workingposition. It is another object of my invention to provide means,comprising a foot-lever, for lifting and locking the cutter-bar ineither of a plurality of positions so arranged and constructedthat'wh'en the cutter-bar is" moved into either of said positions thefoot-lever will be held in elevated position ready for an operativestroke. It is another object of my invention to provide means. forlifting the cutter-bar by the use of two levers, by oneof whichleversthe bar can be held temporarily in raised position, thearrangement and construction be-* ing such that when the other lever isreleased the cutter-bar will be automatically locked in raised position.It is another object of my invention to provide a construction of thetype just described so arrangedand con structed that upon a subsequentstroke of the last-mentioned lever the cutter-barwill be released forits downward movement. It

is still. another object of my invention to im prove mowing machines insundry details hereinafter pointed out. The preferred meansby which Ihave accomplished my several. objects is illustrated in the drawings andis hereinafter'f specifically described, That which I believe'to be'newand desire to cover by this application is setiforth in.

and as indicated by dotted lines in Fig.1 it comprises axlarge bevelgear 20 that is in mesh with abevel pinion 21 fixedly mounted on aforwardlyextending shaft22 that thus receives power from the-gear system19, the shaft 22 having fixedly mounted on its forward endxa drivingvhead in the form of a crank wheel 23 which is connected b'f nledils of apitman 24 with a sickle 25 s dably' mounted in a cutter-bar 26 which bythe frame.

is mounted in position as hereinafter described. The frame 15 isprovided, in the construction shown, witha tongue27 of any suitable typeby means of which the machine' is to be drawn across the field, and isfurther provided with a seat 28 of any. suit able type.

The means upon the frame 15 comprises a yoke 29 (see Fig. 2), such yokebeing pivotally mounted upon the forward turned end of a push-bar 30 andthe adjacent end of a drag-bar 31 which in turn is pivotallyconnected atits opposite end with the frame 15 in front of the crank Wheel 23. Theyoke 29 is further connected with the frame 15 by means of a link! 32pivotally'connected at its forward end with an arm 33 that is preferablyformed integrally with said yoke, the link 32 being connected at itsrear end with a lever 34 of any suitable type pivotally 'mounted uponthe. frame 15 and adjustable. relative thereto along a segmental rack 35carried As will be readily under stood, byan adjustment of the lever 34the yoke 29 can be tilted on a transversely ex tending axis relative tothe framework. The cutter-bar 26 is'pivotally' connected to the yoke 29upon an axis extending longitudinally of the machine by means of asuitable shoe 36 to which theinner end ofsaid cutter-bar is fixedlyconnected.

By reason of the bars 30 and 31' being pivotally connected with theframe 15,. the yoke 29 andthe cutter-bar 26 are movable upa-nddownrelative to the frame 15, while at the same time thecutter-bar 26. ismoveble' relative totheyoke 29 upon the longitudinally ext'ending axisof the shoe 36 upon said yoke. The parts sofa-r described are of theordinary type well understood in the art and form in and of themselvesno. part of my present invention.

' The means for raising the yoke 29 and the cutter-bar 26 relative tothe frame 15 comprises a bell-crank lever or sector 37 which ispivotally mounted upon the framework 15. The forward end of theforwardly-extending arm of the sector 37 is provided with a flexibleconnector 38 which extends about a spirally-grooved sheave 39, and fromthence to the shoe 36 to which it is connected at a point beyond theaxis of the shoe, such flexible connector in its passage to thepointwhere it is attached to the shoe I passing over a suitable arm orstandard 40 fixedly mounted upon the shoe, and which may'begrooved asshown to'properly receive and guide the said flexible connector, orwhich may, if deemed advisable, be provided I with a suitable groovedpulley for the con nector' to run over. By reason of passing overthisupright arm or standard a pull is had'on the shoe of a character thatwill cause the cutter-bar to turn on'its pivotal connecfor mounting thecutter-bar;

. which is mounted upon the drag-bar 31 adj acent-to the yoke 29. Thearrangement and construction of the parts are such that, upon a turningof the sector 37 in counterclockwise direction in Fig. 2 from theposition shown therein, the sheave 39 2LI1Cl 'tllB yoke '29 are movedupward relative to the framework, carrying upward with them the shoe 36and the cutter-bar 26. When in the upward movement of the parts as justdescribed the push-bar 30 comes in contact with a suitable stop formedon the underside of the framework so as'to be incapable of furtherupward movement, a continued rotation of the sector 37 incounterclockwise direction in Fig. 2 serves through the medium of theflexible connector 38 to turn the shoe 36 relative to the yoke 29 uponits horizontal axis, whereby the cutter-bar 26 and th sickle 25slida'bly carried thereby are swung upward substantially in a verticalpositionas shown in Fig.3, the sheave 39 being adapted to ro tate topermit of such turning movement. The stop referred to with which thepushbar 30 comesin contact is, in the construction shown, the bearingplate '52 that is hereinafter referred to.

Meansis provided in connection with the sector 3-7, adapted upontherocking of the sector in coi'interclockwise direction in Figs. 2, 3 and4, to throw out of operation the sickle-driving mechanism. This meanscomprises a link 42 the turned forward end of which is slidably mountedin a slot 43 in thesector 37. The link 42 is pivotally connected at itsrear end with an arm 44 depending from b a foot-lever 45 pivotallymounted upon the framework 15, the construction being such that when thesector 37 is" turned in counterclockwise direction in Fig. 2,.thefoot-lever 45 will be rocked about its axis also in counterclockwisedirection in said figure. By reason of the slottedcon nection of thelink 42 with the sector 37, the foot-lever 45 is adapted to be operatedindependently. of the rocking of the sector 37 -w'hen such sector standsin the position rection in Fig. 2, the rod 48 will be movedlongitudinally to open the gear system, serving thus to stop thereciprocation of the" 3 sickle relative to the cutter-bar 26.

When the foot-lever 45is turned in clockwise direction in said Fig. 2 bytherocking .systeimtlmsstarting the reciprocation of the sickle 25. Thislast-named longitudinal movement may be efi'ected by means of acoiled-spring (notshown) orby any other suitable means. In the preferredconstruction the arrangement is such that the rod 4:8

opens and closes the; gear systemautomat-ically at about the time thecutter-bar starts" to turn onits horizontal axis relative to the yoke29. .Itis thusseen that the cutter-bar can be raised. a short'distance,such as is necessary for a proper turning at corners,

without throwingtthe cutting apparatus out of. operationw A spring 49'connected to the sector and to the framework-l5 in rear. of such sec- Itor serves to assist in turning the'sector in counterclockwise directionin Figs. .2and 3, serving-also to counterbalance a portion of the weightof the cutting apparatus in order to decrease the friction of thecutterbar upon the ground and in order to. transfer the principalweightof the cutting apparatus to the frame where'it adds traction tothe wheels.

The means for supporting the sector 37 in position upon the frameworkand for rocking such sector for operating the cutterbar comprises afoot-lever 50, shown in detail in Fig. 9. Thisfoot-lever comprises atransversely-extending portion 51 which is journaled upon the framework15 by means of a bearing-plate 52 as is probably best shown in Fig. 8."As is best shown in Fig. 9, the end portion 53 of thelaterally-extending arm 51 of the lever 50 is. offset relative to theaxis upon which the lever is connected with the frame 15, the part 53serving to provide a journal for thesector 37 in an offset or crankedposition relative to the pivotal mounting of the lever 50. The sector 37is provided with a handle or lever 54: fixedly mounted thereon Withinconvenient. reach of an operator upon the'seat 28. As will be readilyunderstood, when the operator swings the lever '54 backward from theposition shown in Fig. 2 into the position shown in Fig. 3, the sector37 will be given an operative stroke for first raising the yoke 29 andthe cutting apparatus and then swingingthecutter-bar upward relative tothe yoke 29, as above described. p

Inasmuch as the sector 37, by which the weight of the cutting apparatusis supported d uring'thelifti-ng operation, is mounted upon an offsetportion'of theilever 50,such. offset portion 53 of the lever 50 willhave a tendency always to move toward its lowermost position relative tothe portion '51 of the lever, exceptas pressure is applied to thelever5O by thefoot of the operator or as the sector 37 is supportedagainst downward movement by someother suitable stop ping or supportingmeans. Such supporting means is provided, comprising a combination stopand latch member 55 rigidly mounted upon the framework 15. The sector..37 is provided with a suitable flange 56 whichrests upon the upperendof the member" 55 when the cutting apparatus is in operativepositionyasis shown" in Fig. 6, serving to hold the ofi'setportion 53 ofthe foot lever in raised position relativeto the portion 51 1 as isclearlyindicated. in said Fig. 6; When the lever 5 and the sector 37 arerocked in counterclockwise direction in Fig. 6, the flange 56 travelsalong the up per. end of the stop 55 until'a step 57 in such flangearrives opposite the rear face of the stop 55, whereuponthe sector 37 isadapted to move downward relative tothe stop .55 by reason of the weightof the cutpressure is appliedtothe foot-lever 50 so as to hold the leveragainst turning. When the step'57has engaged the rear edge of the stop'55, the lever 54'c'an then be released and the sector will be heldagainst movement in clockwise direction, the cutting apparame being thusheld in its elevated position.- If the lever 54: be then given a furtherbackward movement, the intermediate portion of the fiange56 travelsbackward along the stop member 55 serving to hold the portion 53 ofthe'foot-lever in'its raised position. When the'sector 37 has beenturned sufficiently to bring a step 58 in the flange 56 opposite therearedge'of the stop or latch member 55, the sector 37 is againpermitted tofmove downward, carrying the step 58 into latchingengagementwith the member. 55,.except as such movement is prevented by downwardpressure uponthe foot-lever 50.

The step 57 is so positioned on the flange. 56-as to come intooperativeposition relative tothe latch member 55v at about the time wlienthe yoke29 reaches its uppermost positionand before the cutter-bar 26 begins toturnupon its axis relative to the yoke 29. The step 58 is sopositioned-as to come into operative engagement with the latch member 55at'about the time when the cutterbar 26 reaches its substantiallyvertical inoperative position. As will be seen byan inspection of Figs.5, 6' and 7, the flange 56 is not concentric about the portion 53 of thefo otlever 50, but has a slight cam action serving to raise the portion53 gradually relative tothe portion 51 of the foot-lever as .the' sector37 is moved in counterclockwise direction in said'figures' through the.me-

move gradually downward as the portion '53 is moved upward, except thativhenthe steps 57 and 58 are brought into engagement with the stop orlatch member 55 the rear end of the foot-lever 50 willabe given abruptmove: ments upward corresponding to the abrupt downward movements of theportion- 53; Whenever the sector 37 is held in turned position by reasonof the engagement of one of the steps 5758 with the latch member 55serving to hold the cutter-bar in elevated position, and when itisdesired to lower the cutter-bar, this can be accomplished by adownward pressure upon the rear end of the foot-lever, such downwardpressure serving to raise the stepped flange 56 relative tothe member 55whereby the sector is free to swing in clockwise direction in Figs. 5,6and 7 for permitting the dewnwardmove ment of the cutting mechanism.

The foot-lever 50 is also adapted to assist,

in the initial movement of the sector37= in counterclockwise directionin Figs. 2, 3 and 4, or to give such movementto the sector independentlyof the lever 54, this result being effected through the medium of an arm59 fixedly mounted upon the'end of the offset portion 53 of thefoot-lever, such arm normally underlying a set-screw 6O adjustablymounted in thesector 37. With the parts in the position-shown in Fig.v6, in which position such parts stand when the cutter bar is in itsoperative cutting position, upon a downward stroke of the rear end ofthe lever 50 the arm 59'is moved up"- ward serving to swing the sector37 rear-- wardly about the axis of the portion 51of the foot-lever. Aswill be readily understood, this serves to raise the flange 56 out ofcontact with the member 55, wherefore the sector 37 is not normallylocked in position upon such a movement of the foot-lever 50. 'When thesector has been swung backward in this manner by the use of the footlever 50, if the operator desires to lock the cutting apparatus in itsraised position .he can accomplish this result by holding the lever 5aagainst forward movement and by removing the pressure upon thefoot-lever.

The sector is thus held against rocking," but is permitted to movedownward into contact with the stop member 55 as the weight of themechanism turns the lever 50 about the journal portion 51 so as to bringthe portion 53 .to its lowermost point as above described. Thefoot-lever is capable of turning the sector 37 through only a nor-. tionof its stroke, being'capab-le of swing-- ing the step 57 well past therear edge of the stop member 55. If the sector 37 be given a backwardmovement through the medium of the foot-lever 50, the step 57 can bebrought into engagement with'the stop member 55 by a quick upwardmovement of such lever 50 without the necessity for graspanism serves tomove the lever 50 into raised position-whenever the locking is ef-Jfected, and the mechanism 1S adapted many event tobe unlockedforlowering'the' cutting mechanism by a subsequent downward movement ofthe foot-lever50.
